the icons on the steel parts and the sketch on the

Figure 4: FUNCTIONAL PRINCIPLES
All three versions feature one-way locking of the rope.
Under load the friction of the rope rotates the cam to
lock the rope against the fixed camming element. To
gradually release the grip on the rope, unlock the handle
by pressing the safety latch and rotate it (always hold
the free end of the rope).
In case of over-rotation – e.g. panic reaction – the
double stop version (Sirius) passes into the 2nd (anti-
panic) stop while Spark and Spark Tactical do not. By
releasing the handle, it automatically returns in the park
position.
In the other direction (to take in Slack) the rope moves
relatively unimpeded.
Figure 5: OPERATIONAL CHECK
Check that the sides of the housing cannot be slid apart
and the closing button is fully released (the device is
closed correctly).
• Check whether the rope is inserted correctly (according
to the sketch on the housing).
• Before each use, carry out an operational check of the
device by loading it and testing descent functionality
while secured by other means (figure 5a).
• It is essential to assess the reliability and security of
the entire safety system you are relying on. Non-
exhaustive list includes:
- adequate resistance of the anchors (EN 795, ANSI/
ASSP Z359.1 or according to valid regulations) and the
structure they are fixed on;
- correct (higher) positioning of the anchors to prevent
pendulum effects or arrest a fall;
- correct positioning of the ropes:
• removing or protecting them from sharp edges or
points of chafing;
• preventing ill running of the descender (e.g. loaded
over an edge or at an angle to the rope);
• rope redundancy in rope access;
• to tie a stopper knot at the free end of the rope.
Any overload or dynamic loading of the descender may
damage the rope!
